PPS refers to "pulse per second". IF you have some external source which delivers a signal once per second (eg a gps receiver with PPS output) then ntpd will use that to make sure that the clock registers .000000 at the beginning of that pulse. If the PPS is accurately timed, then your system time will be accurately set as far as the seconds turnover is concerned. > > Thanks > Prab > > _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
